How can I find the code which caused the Heartbleed Bug before the fix was made?

Question

I can find the open source code for t1_lib.c, but is there a place where old code is stored? I need to do a project where I demonstrate to the class what can happen if this bounds check is not done, but I am not sure how much was added to the file to solve the problem. I am taking an advanced data security class, and this is the project I was assigned. Thanks!

Here is the Github commit that fixes the bug. It shows both "before" and "after" states of the code.
